1.4.2 LAN2 Accommodation
LAN2 mainly accommodates the devices for operation/administration and some for call controlling. They need
to keep links with Telephony Server when system changeover is performed in dual configuration system. In
each case where the system is in single configuration or dual configuration, IP address (ACT) is basically as-
signed to the devices as Telephony Server address.
